A gene is a basic unit of heredity in a living organism that normally resides in long strands of DNA called chromosomes. Genes are coded instructions that decide what the organism is like, how it behaves in its environment and how it survives.
Chromosomes are the way DNA in a cell is ordered. DNA is a long string of nucleotides placed in a specific order to code for our genes. A chromosome is one such very long DNA string with multiple genes.
